Fentanyl (N-Phenyl-N-[1-(2-phenylethyl)-4-piperidinyl]propanamide) represents an ultra-potent synthetic opioid analgesic with established pharmaceutical applications in anesthesia, perioperative pain management, and chronic pain treatment (Duragesic®, Actiq®, Sublimaze®). As a full μ-opioid receptor agonist with 50-100 times the potency of morphine, fentanyl serves as a critical reference standard in forensic toxicology, pharmaceutical research, and clinical pharmacology. Biosynlab delivers pharmaceutical-grade fentanyl with certified ≥99.0% purity, supporting cutting-edge research across USA (DEA Schedule II licensed institutions), United Kingdom, European Union, and international scientific and clinical markets.
The unique 4-anilidopiperidine structure of fentanyl distinguishes it from morphinan opioids, conferring high lipophilicity, rapid onset of action, and short duration of effect. These pharmacokinetic properties make fentanyl invaluable for specific clinical applications while requiring extreme caution in handling due to its potency (lethal dose estimated at 2-3mg for opioid-naïve individuals). Biosynlab’s rigorous quality control ensures batch-to-batch consistency essential for quantitative research, therapeutic drug monitoring, and forensic applications where precision is paramount. Research institutions and forensic laboratories in London, Berlin, Amsterdam, New York, and San Francisco rely on Biosynlab fentanyl for quantitative analysis, novel fentanyl analog research, and monitoring of the evolving synthetic opioid landscape.
Chemical Properties & Structural Characterization
Fentanyl belongs to the 4-anilidopiperidine chemical class, a distinct structural scaffold from traditional morphinan opioids, characterized by a piperidine ring with an anilide substitution at the 4-position and a phenethyl group on the piperidine nitrogen.
Key Structural Features:
- Core Scaffold: 4-anilidopiperidine backbone
- Substitutions: N-phenylpropanamide (anilide), N-phenethylpiperidine
- Functional Groups: Tertiary amide, tertiary amine (piperidine), phenyl rings
- Stereochemistry: Achiral molecule (no stereocenters)
- Salt Forms: Citrate (most common), hydrochloride, base
- Physical State: Crystalline powder (highly potent, handle with extreme care)
Analytical Characteristics:
- UV Absorption: 250 nm (anilide chromophore), 280 nm shoulder
- Retention Time (HPLC): 7.2-8.0 minutes (C18 column, gradient method)
- Mass Spec m/z: 337.2 [M+H]+ (base), 188.1 [phenethylpiperidine]+, 105.1 [phenyl]+, 91.1 [tropylium]+
- NMR Signatures: Piperidine protons (1.4-2.8 ppm), phenethyl protons (2.6-2.9 ppm), phenyl protons (7.1-7.4 ppm), N-phenyl multiplet (7.4-7.6 ppm)
